Gastric Bypass or
Roux-en-Y
Gastric Bypass Surgery
Overview
Perth Surgical & Bariatrics offers several options for weight loss. One of the most well-known is Roux-en-Y gastric bypass. Designed to reduce the amount of food you consume by cutting away a part of the stomach, gastric bypass is a permanent procedure that helps patients achieve and maintain weight loss goals.
- Gastric Pouch
- Stomach Bypassed
- Jejunum
- Duodenum (bypassed)
When gastric bypass is performed using the “open” approach, an incision is made in the abdomen extending from just below the sternum to an area slightly below the belly button. A stapling device is then used to create a tiny stomach pouch by partitioning the existing stomach, essentially changing its size and preventing too much food to be consumed. The “laparoscopic,” or minimally-invasive approach follows the same guidelines as the “open surgery,” but is performed internally.
Using five small keyhole-sized incisions, the bariatric surgeon relies on a camera that is inserted into one of the incisions to see inside the body, while using several small instruments inserted through the other incisions to perform the procedure.
Gastric bypass/Roux-en-Y surgery has many potential benefits.
Length of stay
RNY, SIPS(SADI-S) and other gastric bypass patients only need to stay 1-2 nights in hospital.
Most patients recover fully in 2 to 4 weeks.

Risks and Considerations
Gastric bypass patients may experience dumping syndrome, a very uncomfortable result of consuming high fat and high sugar foods.
Gastric bypass is major surgery and carries all the risks of a surgical procedure. Please contact us for more information on these risks.
Possible Complications
Cardiovascular problems (especially with unidentified, pre-existing heart disease): heart attack, stroke or death
Respiratory problems: pneumonia, pulmonary embolus
Wound problems: wound infection(<5%), hernia development (1% for laparoscopic Surgeries)
Circulation: problems includes blood clots in legs and blood clots migrating to lungs
Stomach/intestinal problems: leak from stomach or intestinal surgical sites requiring additional surgery, intestinal blockage (1-2%), stoma stenosis from scarring (10%), dumping syndrome (cramping, bloating, and diarrhoea after eating )
Nutritional problems: excessive weight loss, vitamin and mineral deficiencies (may need ongoing medications or injections), hair loss, bone weakening, gallstones or kidney stones
Injury to nearby organs: spleen requiring splenectomy (<1%), significant liver-bleeding (<1%), or potential for transfusions (<5%)
Numerous other less-common complications
Risk of death for laparoscopic gastric bypass: 0.5–1%
Difference between mini gastric and gastric bypass surgery
Mini Gastric Bypass surgery and its procedure.
Mini Gastric Bypass Surgery offers a minimally invasive approach for individuals seeking substantial and sustainable weight loss. This procedure involves resizing the stomach and redirecting a portion of the intestines, facilitating effective weight management.
Preoperative Evaluation:
- Patient Selection: Patients who meet the BMI criteria and have comorbidities like type 2 diabetes, hypertension, and sleep apnea.
Preoperative Assessment: Detailed evaluation, including medical history, physical examination, nutritional assessment, and psychological review to gauge surgical readiness and potential risks.
Educational Counseling: In-depth information on the procedure, anticipated results, possible risks, and necessary post-operative lifestyle adjustments.
Surgical Procedure:
Mini gastric bypass surgery involves creating a small stomach pouch and bypassing a portion of the small intestine. During the procedure, the surgeon creates a small gastric pouch (~30 ml) using a linear stapler, typically along the lesser curve of the stomach, while preserving the blood supply to the remnant stomach.
Post-operative Care:
Monitoring:
Regularly monitor vital signs and watch for complications like bleeding, leaks, or thromboembolism.
Pain Management:
A multimodal approach to manage postoperative pain, minimise opioid use, and facilitate early mobilisation.
Fluids and Nutrition:
Fluid and nutrition intake are to be initiated according to protocol, progressing from clear liquids to pureed and solid foods gradually.
Follow-up:
Plan regular follow-up appointments to track weight loss, and nutritional status, and address any concerns or complications.
Long-term Management:
Nutritional Supplementation:
Lifelong vitamin and mineral supplements, including vitamin B12, iron, calcium, and vitamin D, to prevent deficiencies.
Lifestyle Counselling:
Ongoing guidance on dietary adjustments, exercise, and behavior modification to support sustained weight loss.
Monitoring and Surveillance:
Monitor weight loss progress, and comorbidity resolution, and manage long-term complications like reflux, dumping syndrome, or malnutrition.
Advantages of Mini Gastric Bypass
Mini gastric bypass surgery merges the advantages of traditional gastric bypass with a simpler surgical process, reducing complications and recovery time. Apart from promoting significant weight loss, this surgery can address obesity-related conditions like type 2 diabetes, hypertension, and sleep apnea. Patients often experience rapid initial weight reduction and enduring long-term outcomes.
